CNC Programmer

Turn engineering intent into perfect tool paths. Own the code behind every cut.

Union City, CA · $38 – $48/hour · 3+ years

Reports to: Senior CNC Programmer / Engineering Manager

About This Role

Write, optimize, and verify CNC programs for 3, 4, and 5-axis milling and turning centers. Translate engineering intent into efficient tool paths, select appropriate tooling and cutting strategies, and run prove-outs on the shop floor.

Work closely with machinists and engineers to reduce cycle times, improve surface finishes, and push the boundaries of what our machines can do. We're a startup — you won't just write programs, you'll build the programming standards and best practices from scratch. Everyone gives 110%.

This position bridges CAD/CAM engineering with hands-on manufacturing. You'll have real ownership over how parts are programmed and proven out, with direct impact on quality, efficiency, and profitability.

Key Responsibilities

  • Write CNC programs for 3, 4, and 5-axis milling operations
  • Program multi-axis turning centers including live-tooling lathes
  • Select optimal cutting tools, speeds, feeds, and machining strategies
  • Run prove-outs on the shop floor and make real-time adjustments
  • Optimize programs for cycle time reduction and surface finish improvement
  • Collaborate with engineers on DFM reviews and process planning
  • Create and maintain tool libraries and cutting parameter databases
  • Customize post-processors for specific machine configurations
  • Verify programs using simulation software before production
  • Work with machinists to troubleshoot and resolve machining issues
  • Document all programs, setups, and special instructions
  • Support new product introduction (NPI) and first-article processes
  • Develop standard programming templates for recurring part families
  • Train machinists on program execution and G-code interpretation

Requirements

  • 3+ years of CNC programming experience (mill and/or lathe)
  • Proficient in Mastercam, Fusion 360, or equivalent CAM software
  • Solid understanding of cutting tool selection and speeds/feeds
  • Experience programming 3, 4, and 5-axis operations
  • Strong GD&T interpretation and DFM knowledge
  • Ability to prove out programs on the machine and make real-time adjustments
  • Experience with post-processor customization
  • Strong problem-solving and analytical skills
  • Excellent communication skills for cross-functional collaboration
  • Attention to detail and thorough documentation habits

Preferred Qualifications

  • Experience with high-speed machining (HSM) strategies
  • Simulation software experience (Vericut, Mastercam Simulator)
  • Knowledge of Swiss-type lathe programming
  • CAD modeling skills (SolidWorks, Fusion 360)
  • Experience programming for aerospace materials (titanium, Inconel)
  • Familiarity with AS9100 or ISO 9001 quality standards

Benefits & Perks

  • Competitive pay: $38–$48/hour depending on experience
  • Comprehensive health, dental, and vision insurance
  • Paid time off and holidays
  • Overtime opportunities (time and a half)
  • Paid training, certifications, and CAM software licenses
  • Modern CNC equipment and cutting-edge tooling
  • Startup culture with performance bonuses and growth opportunities

Additional Information

Work Schedule: Monday – Friday, standard business hours. Overtime available.
